Give examples to show that friction is both a friend and a foe.

• With the help of friction, we get able to grip and catch any object.
• We can walk comfortably on the floor with the help of friction offered by the floor's surface.
• Friction helps to minimize the speed or to stop any moving object.
• We get able to write on paper due to friction.

Friction as a foe:

The following examples show that friction acts like a foe:

• Friction causes wear and tears in objects.
• Friction is the main cause of damage to the parts of machines and tools which further require money to get repaired.
• The speed of moving objects gets reduced due to friction, so more force is required.
• Friction produces hurdles in any freely moving object.
